January 24,1929. Serial No. 334,848.

This invention relates to advertising devices and particularly to devices for advertising L and displaying electric suction cleaners and Operating parts thereof. i f The primary object of the invention is yto provide al1- advertising device of novel and improved construction. which will demonstrate the suction power, or lifting capacity, of an electric suction cleaner. v f Another object is to provide a device including a suction cleaner and parts connected thereto which will'y cause a 'weighted article to travel through certain predetermined positions bythe suction created'by the cleaner k1.5I and then cause kthe object to return to initial positionby gravity. 'c A further 'Objectis' tofprovidea device including a suction cleaner and detachable parts thereof, which will continuously lift a 2o steel balltby the suction of the cleaner durylng ,operation thereofand then release the ball at the limit of its upward travel, wherebythe ball will be returned lto initial position by gravity over a certain deiinedand interrupted route.

` Otherv objects of the invention are to provide a'device which will cause a steel ball totravel a predetermined position at the inlet of a suction hose where it will be lifted by suction from a suction cleaner; ywhich will release the ball after it has traveled a certain distance and prevent it from coming in contact Vwith the opreating parts of the cleaner.; which has a. trap or valve which closes 35 of its own accord after the ball passes therethrough so as to maintain a suction in the hose; .and which causes the ball to strike an obstruction and ythen fall into Va receptacle where it will return to the inlet by j l40 gravity where the operation will again be repeated.

Other objects and advantages will hereinafter appear. Y

In accordance with the invention the de- ,4,5 vice has a frame or stand which supports an electric suction cleaner. A dusting hose which is secured to the frame has one end thereof connected to the cleaner and its other end connected to a tray or plate which #'50 is arranged at the lower end of the frame.

of the ball.-

The tray is provided with an inclined groove so that a ball or other object to be lifted by the suction of the cleaner will always be fed to the open end of the dusting hose. After the ball is'carried through the hose it is re- .55 turned to the tray by gravity and the operation is repeated. As the ball returns it strikes an anvil and bounces into a basket or other receptacle thereby attracting attention and making the device more interesting. an The ball is substantially as large as the internal diameter of the hose in order to permit. proper lifting of the ball by preventing the air from being drawn around the sides The accompanying drawing illustrates Va selected embodiment of the invention and the views therein are as follows:

Fig. 1 is a front elevation .of the device.

Fig. 2 is a side view thereof. y0

Fig. y3 isa detail plan view on the line 3 3 of F i0. 1 showing the adapter connection. f

Re erring to the drawing, 5 designates gen` erally a stand or frame comprising a face plate 6 and a supporting member 7 to which a 75 suction cleaner 8 is rigidly attached. An adapter member 9 is secured to the eye of the fan casing 10 and is provided with a branch 11 to which a dusting hose or tube 12 is attached. A steel ball 13 is adapted to be lifted bythe suction in the hose 12 and a screen 14 fastened to a member 9, is arranged at the lower end of the fan casing to prevent ythe ball from coming in contact with a fan which operates in the casing 10. S5 After the ball is lifted by the suction in the hose 12 it will drop, due to its own weight, in

the vertical portion 15 of the adapter 9 and cause a liap valve 16 to open and temporarily release the suction in the hose 12. An anvil 17 is located immediately below the valve so that when the ball drops through the valve it will strike the anvil and bounce into a catch basin, or other receptacle 18 where it will roll to the rearward side of the plate 6 into a 95 tubular member 19 and later be discharged on the tray 20 which is located at the lower end ofthe face plate 6.

The tra'y 20 is provided with a groove 21 whichvslopes toward the inlet end 22 of the nl Y hose12. After tlieball passesthrough the Y TheY steel Yball 13 isplaced tubular member 19 it- Will ro1l iii the v groove 21 to the inlet 22'vvhere the suction in the hose 12 will again raise the ball and repeat the opi eration. Y

The hose .,12is preferably providedjvvith 'a o-lass 2zisthe ball'is being lifted by the suction in the hose its movement through ythe glass portion may be plainly fseen. An opening 2li is provided through the face plate 6, and a `light bulb and a reflector 26 are arranged on therearvvard side of the plate 6 to illuminate the glass portion 23 so that the-upward 15 movement of the ball yasit passes therethrough may be easily'seen.

The operation oft-he device is as follows: in the groovev 21 in the tray 2Q. and rolls tolvvard the inlet 22 of the hose 12,'vvherel it vvill be lifted by the suction until it reaches the'topfend of the hose and enters'adapter 9 at the under side of the suction cleaner. After vthe ball has reached the'end of'its upward travel it vvill drop into the vertical portion-15 of thenieinber 9 and fall through the valve16. After passing through the valve 16 it Will strike the anvil 17 `and bounce into the catch basin 18. This catch basin is provided with an inclined portion 27 which leads to the end 28 of kthe 'tubularv member 19 fivherej the'ball will descend by gravity to the plate-20 Where the operation is again repeated. 4

The invention provides a device which is exceedingly interesting'and demonstrates the lifting or suction poiver of a suction cleaner. The parts are properly positioned so that the steelball Will alvvays'travel vthe saineV Way,

Vout departing in said hose, means for returning and as it rpasses through the illuminated glass portion of the tube it Will attract considerable attention.r V Y I Changes may-be made in the form, construction and arrangement of the parts Withfr'oin the spirit of the invenf tion or sacrificing any of itsv advantages, and

the right is hereby7 reserved to make all such changes as fairly fall Within the scope of the following claims.
